Suddenly there is a white bar about 3 inches wide through the middle of my screen from top to bottom.  Tried restoring to a previous point last week, no luck.  Computer is not even 3 months old.  Any suggestions?

    What is the full model number of your device? I am providing the steps assuming that it is laptop.
    >>First, please try a simple power reset and check the issue. Shutdown the laptop. Disconnect the charger. Please check for a battery reset PIN hole at the bottom of the device.The reset hole would have a battery symbol next to it. Insert a paperclip into the hole and press for four seconds. Let the computer sit for 5 minutes with no power. Reconnect the charger, power On the laptop and check the issue.
    Check with External display.

    >>Try connecting an external monitor to the laptop's HDMI port and see what the display is like.
    If it displays OK then you either have a faulty video cable, a faulty video cable connection at either end motherboard or screen, or a faulty LCD screen.
    If it displays the same as the laptop's screen, then you either have a GPU problem most probably CPU as they are integrated or a motherboard problem.
    Check in BIOS page.

    >>Press and hold the Power Button for 5 seconds to turn your computer completely off. Power on the system. As soon as the first logo screen appears, immediately press the F2 key to enter the BIOS. Let me tell you one thing that BIOS has no link with Operating System.
    So, if you notice the vertical lines are still appearing while you entered the BIOS, it means the problem is related to the hardware. If you see no vertical lines in BIOS, it shows that it is a software issue.

    If the device is in warranty, please contact Acer support in your region and they will help you fix the issue under warranty.
